Mapping Slums – Data preparation in QGIS
In this next step you will use the previously prepared data to train the random forrest model. This model will later on be applied to predict the prospective location of slums in Lagos. You’ll learn how to create raster point values that correspond to slum or non slum pixels of the image and how to convert them into a .csv-file. This will enable you to continue processing the data in R-Studio.
